What is a nautical mile?
A nautical mile is the distance unit of sea and air navigation, chosen so it tracks latitude on a chart.
Definition: Exactly 1,852 meters, fixed by the 1929 International Extraordinary Hydrographic Conference. It approximates one arcminute of latitude.
Where it is used: Marine and aviation navigation, maritime boundaries, and the basis of the knot (one nautical mile per hour).
Worth knowing: About 15% longer than a statute mile — mixing the two is a classic navigation error.
What is a yard?
A yard is three feet, the mid-range imperial length unit familiar from sports fields.
Definition: Exactly 0.9144 meter since the 1959 International Yard and Pound Agreement, which harmonized the US and Commonwealth definitions.
Where it is used: American football, fabric and carpet, landscaping materials, and golf distances.
Nautical Miles vs Yards
The nautical mile is a specialized unit while the yard is an imperial unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
